Tiv thaiv Cartridge Heater Premature Failure in Industrial Environments
Kev rwb thaiv tsev - tswb tiv thaiv lossis lub tshuab cua sov uas tsis ncav cuag nws qhov taw tes yog feem ntau yog thawj cov cim qhia txog kev poob qis. Ib qho ntawm ob peb lub hauv paus ua rau tuaj yeem zam tau nrog kev ceev faj thiab kev teeb tsa feem ntau pom thaum tshawb xyuas. Thaum cov kev hloov pauv tau tswj tau, lub tshuab hluav taws xob cartridge tau tsim kom kav ntev.
Cov khoom no yog tsim los ntawm stainless- steel los yog Incoloy sheath uas muaj cov ntaub qhwv nruj nreem ntim rau hauv compacted magnesium oxide. Thaum lub tsev nyob zoo, swaging densifies lub rwb thaiv tsev kom yooj yim rau kev hloov mus rau sab nraud. Txawm hais tias nws muaj peev xwm ncav cuag qhov kub siab tshaj plaws ntawm qhov kub ntawm 760 degree, lub neej tiag tiag yog nyob ntawm kev ua haujlwm ntau dua li ntawm qhov ntsuas ntsuas.
Kev siv hluav taws xob qhuav, xoob haum, noo noo nkag mus, cov hlau lead overheating, thiab qhov hluav taws xob tsis sib haum yog hom tsis ua haujlwm. Thaum hluav taws xob tau qhia ua ntej lub tshuab rhaub tau muab tso rau hauv lub qhov loj kom zoo, qhov hluav taws kub qhuav tshwm sim; Cov kub sab hauv tau nce sai sai thiab lub kauj yuav qhib rau hauv ib lub vib nas this. Lub sheath yuav tsum ua hauj lwm kub ntau dua li cov txheej txheem hu rau vim ib tug xoob bore tsim ib tug huab cua sib txawv nrog ib tug thermal conductivity uas yog hais txog ib txhiab ntawm cov hlau. Thaum lub sij hawm cia, magnesium oxide yooj yim absorbs ambient humidity; Thaum lub zog thawj zaug, qhov nqus dej noo txo ​​cov dielectric zog thiab tuaj yeem ua rau luv luv. Cov hlau lead uas nquag flexed los yog raug rau qhov kub thiab txias ua nkig thiab tawg. Thaum lub tshuab hluav taws xob 120 V txuas nrog 240 V qhov, lub zog yog muab faib ua plaub, uas yuav luag tsis sib xws ua rau muaj kev kub ntxhov ceev.
Raws li kev paub dhau los, feem ntau ntawm huab cua- qhov teeb meem sib txawv tuaj yeem daws tau nrog kev ua tiav ntawm qhov chaw du thiab lub diametral clearance ntawm 0.025-0.076 hli tom qab precision reaming. Txhawm rau kom ntseeg tau tias tag nrho cov cua sov ntev nyob hauv cov hlau, lub rhaub yuav tsum tau zaum kom zoo. Ua ntej yuav ntxig, lub bore yuav tsum tau ntxuav kom huv si. Kev pheej hmoo noo noo yog tshem tawm los ntawm kev khaws cia rau hauv lub hnab ntim nrog cov desiccant thiab kev tswj hwm qis -voltage qhuav- tawm. Qhov kev txiav tawm yog kev tiv thaiv los ntawm cov seem txias txaus thiab siab -kub txhuas rwb thaiv tsev. Lub voltage yuav tsum precisely phim lub nameplate.
Kev degradation raug kuaj pom ntxov dhau los ntawm kev soj ntsuam kev ua haujlwm ntawm kev tiv thaiv khaub thuas thiab kev ntsuam xyuas pom ntawm cov xim tawv thiab cov hlau lead. Ib qho kev tawm tsam ntawm ntau tshaj 10% los yog discoloration tshaj oxidation raug qhia tias chav tsev yuav tsum tau hloov ua ntej nws malfunctions thaum siv. Cov chaw nres tsheb uas tsis tau npaj tseg tau txo qis ntxiv los ntawm kev ua kom tsim nyog tsim nyog cov khoom siv hluav taws xob tso rau ntawm tes rau qhov chaw tseem ceeb.
Lub tshuab rhaub cartridge tuaj yeem ua haujlwm tau ntev ntev yog tias kev teeb tsa kev tshem tawm, kev tiv thaiv ib puag ncig, thiab kev sib txuam hluav taws xob ua raws. Lub tshuab cua sov uas nws txoj kab uas hla, qhov ntev, qhov ntom ntom, thiab kev txiav tawm tau kwv yees rau qhov tshwj xeeb thermal thiab mechanical ib puag ncig pab cov cuab yeej ntawm ntau qhov ntau thiab tsawg, cov ntaub ntawv, thiab qhov kub thiab txias profiles, uas ua rau kev ua haujlwm tas li yam tsis muaj kev cuam tshuam ntau zaus.
